4. Axial Play Check and Adjustment
Axial or end play on shafting can result in noise, wear,
and faulty sewing.
Tools required: (2, and 2.5mm handle allen)
Check:
1. Check the arm-shaft by pushing and pulling on the hand
wheel. See Figure 4.1. If a correction is necessary:
•
Loosen the thrust collar (See figure 4.2)
•
Adjust so that no play is detected.
Care must be
taken on the first screw that is fixed on an inclined
flat so as not to tighten too tight at first.
•
Provisionally set the first screw, tighten the second
screw fully tight.
•
Tighten the first screw.
2. Check the transmission shaft by pushing and pulling
axially on the gear as shown in Figure 4.3. If a
correction is necessary:
•
Loosen the second screw on the gear first, and use
the first screw (screw on flat) to adjust out any play
by moving the gear outwards toward the bushing.
•
Tighten the first screw on the flat, and then tighten
the second screw.
3. Check the hook shaft by pushing and pulling the hook as
shown in Figure 4.4. If a correction is necessary:
•
Remove the play by loosening the hook shaft thrust
collar and adjusting out any axial play as shown in
Figure 4.5. (
Note: No shaft flat is located here.)
Note: See torque specifications
chart in the specification section
for torque values.
